Heat-not-burn cigarette filter stick and cigarette comprising same

Abstract

The invention discloses a heat-not-burn cigarette filter stick which comprises a supporting cooling section (2) and a filtering section (3), and the supporting cooling section (2) and the filtering section (3) are wrapped by forming paper (5) to form the filter stick. The supporting cooling section (2) comprises a pipe wall (21) and a pipe cavity (22); a supporting piece (23) is arranged in the pipe cavity (22), the supporting piece (23) extends from one end of the supporting cooling section (2) to the other end of the supporting cooling section (2) in the axial direction by a certain length,and the supporting cooling section (2) is divided into a first part with the supporting piece (23) in the pipe cavity (22) and a second part without the supporting piece (23) in the pipe cavity (22).The first part of the supporting and cooling section (2) can play a role in supporting cigarettes and reducing the temperature of smoke. The second part of the pipe wall (21) is provided with a ventilation window (24), air can be introduced, the ventilation amount is increased, and the smoke temperature is further effectively reduced.

Description

technical field [0001] The patent of the present invention relates to the technical field of production of heat-not-burn cigarettes, in particular to a heat-not-burn cigarette filter rod and a cigarette containing it. Background technique [0002] As consumers pay more attention to health issues and demand for personalized experience of cigarette products, the tobacco industry has continuously responded to the upgrading of consumers' needs and developed various cigarettes with reduced tar and harm. Among them, heat-not-burn cigarettes can provide a healthier smoking experience while satisfying consumers' sensory needs for cigarette products because their cigarettes are heated in a different way than traditional cigarette products. [0003] Existing heat-not-burn cigarette filter rods mainly include a support section, a cooling section and a filter section, wherein the support section not only supports the cigarette, but more importantly gathers the smoke and assists the cool...

AI Technical Summary

Problems solved by technology

Most of the supporting sections in the prior art are paper tubes, which have strong supporting force, but the flue gas cooling effect is average, while the cooling section is mostly gathered polylactic acid film, which is a phase change material. After a few puffs, the polylactic acid The form of the membrane is easy to collapse and block the airflow channel, and the suction resistance is greatly increased, which affects the suction experience, and the cooling effect of the pure polylactic acid membrane cooling section on the flue gas is still not good

In addition, heat-not-burn cigarette filter rods generally require at least three-component compounding to meet the cooling effect, ensure smoke production and filter smoke. This kind of structure is complex and the compounding efficiency is low
